Default NVIDIA High Definition Audio needs Audio Channel Remapping Tool.

I am currently experimenting with:

GT 520 connected to VGA monitor
GT 520 connected to Denon 1909 receiver via HDMI.

Using NVIDIA High Definition Audio with HDMI cable to receiver which supports 7 speakers for 7.0 surround sound setup, subwoofer is not present.

I notice following problem which is probably not related to subwoofer missing though it might be:

The subwoofer channel and side left channel is swapped for some reason.

Unknown is what the cause of this swapping is.

Possibilities could be:

1. Problem with Denon receiver swapping channels.
2. Bug in NVIDIA High Definition Audio driver swapping channels.
3. Bug in Windows 7.

Whatever the cause may be these audio channel issues seem prevalent.

Creative Labs has a THX console which allows re-mapping of audio channels which is a great solition for these kinds of audio-channel swapped problems.

I recommend NVIDIA adds a tool that allows the NVIDIA High Definition Audio Driver to "re-map" audio channels.

So that for example this new tool can instruct the driver to swap the subwoofer channel and the side left channel.

A gui for such a tool could work as follows:

1. The tool walks over all channels and asks the user which channel it should be played out from.

So tool selects input channel, user selects output channel.

This is not ideal but this is how THX console does it.

A better GUI would simply allow channels to be swapped at will... perhaps with arrows indicating where the channels are truely going.

FL C FR SUB

SL SR

RL RR

Another easier way would be with a table.

Above is a typical surround sound setup.

FL = front left
C = center
FR = front right
SL = side left
SR = side right
RL = rear left
RR = rear right

A GUI could contain a tabel as follows:

INPUT OUTPUT
FL FL
C C
FR FR
SL SL
SR SR
RL RL
RR RR
SUB SUB

The input basically represents the input from games/files and so forth.

The output indicates to which speaker it should be channeled (/to which channel).

Now suppose the user has a swapped audio channel problem for whatever reason this new tool would allow the user to swap channels for example, the user can then alter this table as follows:

INPUT OUTPUT
FL FL
C C
FR FR
SL SUB
SR SR
RL RL
RR RR
SUB SL

Hopefully this would solve the problem.

Leaving channels out could also be helpfull to diagnose problems or disable unwanted channels:


INPUT OUTPUT
FL FL
C C
FR FR
SL -
SR SR
RL RL
RR RR
SUB SL

This seems a bit confusing is also a bit confusing but should work.

Bye for now,
Skybuck.

Left speaker had one cable disconnected, this might have been cause, they issue of channels swapped my persist, hope not.

For now experiment is over.

In near future different PC... hope everything will be fine, if not then this tool will definetly be needed otherwise me and many others not happy =D

Bye,
Skybuck.
